Tell me about an idea of yours that made it all the way into everyday use. Which part of getting it there was nothing like having the idea?

Ideas are cheap; the differentiator is the unglamorous carry — persuasion, edge cases, maintenance. The closing clause pulls the answer past the eureka moment, which is the only part a rehearsed version covers well, and into the middle stretch where most ideas actually die.

• What nearly killed it between idea and adoption?
• What did you compromise from the original vision?
• Who uses it now — and would they call it yours?
• What does keeping it running involve today?

A concrete before-and-after that exists in use today, the boring middle described in real detail — pilots, objections, rework — compromises from the original vision named without resentment, and adoption evidenced by other people's behavior, not self-report.

The story ends at the pitch or the prototype, implementation is skated over with "and then people started using it", every compromise is framed as someone else's failure of vision, or "everyday use" collapses under a probe into one demo.
